The EQEP peripheral includes a 32-bit timer (QUTMR) that is clocked by SYSCLKOUT to generate periodic interrupts for velocity calculations. The unit time out interrupt is set (EQEP_QINT_EN_FLG[27] UTOI_FLG) when the unit timer (QUTMR) matches the unit period register (EQEP_QUPRD).
The EQEP peripheral can be configured to latch the position counter, capture timer, and capture period values on a unit time out event. The latched values are used for velocity calculation as described in Section Section 12.4.3.4.4.
